FAQs about EAp2 :

We have installed submeters on our building but the utility bill includes energy use from several other buildings located on the same campus. How do we reconcile this during the LEED review process?

When is it possible to exclude up to 10% of the building from EAp2?

What do I do if the number of building occupants, operating hours, or vacant space changes during the performance period?

If you pursue the streamlined path for an Energy Star label, should the performance period for EAc6 match the 12-month time frame of the label?

How do I account for computers with multiple monitors on Portfolio Manager?

How should I treat vacant space on Portfolio Manager?

Our building includes a large laboratory space. Can our project benchmark under the Labs21 program?

We have an international project and the space type is eligible for an Energy Star rating. Can we pursue Case 1 to demonstrate compliance given the recently released alternative compliance paths for international projects?

We have a number of buildings on a single campus that we would like to certify at the same time. Is it possible to benchmark the buildings at the campus level?

I have a mixed-use building and am wondering if it is possible to pursue the prerequisite through Case 1. How do we proceed?

We have a building that consists of two attached structures and it’s unclear if we have to consider it a single building or if it should be certified as two separate buildings and benchmarked accordingly. How should we proceed?

How long is an Energy Star label valid to use with a streamlined approach for Case 1?

Our building includes heavy process loads that significantly increase the overall energy use in the building. If we submeter these loads, can we exclude this energy use for benchmarking purposes?

EBOM-2009 EAp2:Minimum Energy Efficiency Performance

Office Space With 25% Data Center Changing to 100% Office-June

There are four buildings that are leased by the State and one of the buildings currently has 25% if it as a Data Center. They will be removing the Data Center in June and I would like to know how to classify this building in Energy Star? Shall I just assume the Data Center is gone already and get a low score, that will change in June and go up or change the classification halfway through the Performance Period and consider it an upgrade? I will have to delete that part of the building and increase the Office Space footage at that time and I don't know if the new data will have to start another twelve month period?

The most accurate thing is to change the classification at the time when the data center is changed. You can edit the spaces in Energy Star...just use the edit feature and make sure to classify the change as an "update" (not a "correction", which presumes you used the wrong value initially and want to apply a new value to the entire benchmarking period). Energy Star uses the update information to adjust benchmarking based on the portion of the 12-month period where one value was true versus another. In general, I think project teams overlook the fact that most multitenant buildings will have occupancy or space changes over the 12-month benchmarking period, and these changes should always result in an update to Energy Star inputs. It's a good idea to upload the space revision history in your LEED application to help reviewers see the adjustments you made over the course of the PP.
